IMPROVEMENT IN WIRE CUTTING AND BENDING MACHINES.

Specification forming part of Letters Patent No. 175,302, dated March28, 1876; application filed January 13, 1876.

To all whom it may concern:

Be it known that I, ARTHUR G. RIsLEY, of Ilion, in the county ofHerkimer and State of New York, have invented certain new andaccompanying drawings, which form part of this specification.

My invention relates to an improvement in machines for cutting andbending wire, for making gun-wipers, chimney-cleaners, &c.; and itconsists in the arrangement and combina'tion of parts, that will be morefully described hereinafter, whereby the wire is cut the proper length,and then, after being passed through the butt, is bent and straightened,ready to have the hair inserted, and then twisted.

The accompanying drawings represent my invention.

(t represents the bed-plate of the machine, which may be of any suitableform and construction. Upon this plate are formed the two guides, 1),between which moves the rackbar 0, that is secured to the rear end ofthe plunger cl. Near the rear end of the bed-plate are the standards 0,which form thebearings for the shaft g, to which is secured theoperating-handle j. On this shaft are placed the cog-wheel t, whichoperates the rackbar and plunger, and is provided with a suitable stop,6, and the cam m, that bears down upon the end of the cutting-lever a.This lever a is pivoted to the side of the bearing 0, and is providedwith a flat spring, p, on its under side, for forcing down thecutting-end below the point where the wire passes through the inner sideof the plate g. This plate is slotted at each end, so that it can beadjusted back and forth, and has the flanges 1 raised upon its topedges, through which flanges are made the holes through which the Wireis fed, and straightened as it is passed through. Between these flangesare the dogs 2, made as here shown or in any other manner, so as to letthe wire be freely fed forward, but will not let it slip backward. Uponthe opposite side of the bed-plate is the sliding adjustable stop 1",for regulating the length of the wire to be cutoff.

Upon the top of the bed-plate, on each side of the long groovedguide l,are placed two or more slotted plates, 3, each one of which carries aroller, 4, having either a grooved or a straight side. By means of theset-screws 5 these rollers can be adjusted to suit differentsized butts.

Outside of the rollers is placed a springcatch, 6, which catches behindthe wire after it has been forced in between the rollers, and preventsit from being drawn back with the plunger as it is being withdrawn.

The Wire is passed through to the proper length, cut otl', passedthrough a butt, and the long end of the butt pushed back between the twofirst rollers, when the plunger d is forced forward, which drives thebutt on through between all the rollers. The wire, in being forcedthrough with the butt, is bent, as shown, and compressed tightly dowpinto the grooves in the side of the butt and 111 the plunger, thegrooves in the side of the plunger serving to straighten the wire out.After the wire has thus been put in the butt it is ready to be. taken tothe twisting-machine, where the bristles are inserted and the wirestwisted, so as to hold them in position, when it is ready for thetrimming-machine, where it is finished. By screwing a handle into thehollow end of the butt it is ready for use.-

Having thus described my invention, I claim-- 7 l. The combination ofthe wheel, rack-bar, plunger, and one or more sets of rollers, wherebythe wires are bent in the butts, substantially as shown.

2. In combination with the rollers and plunger, the spring-catch 6,substantially as described.

3. The combination of the slotted slides, carrying the rollers, with theadjusting setscrews, substantially as set forth.

4. The combination of the plunger, rollers, and grooved guide,substantially as specified.

5. The combination of the cutting-lever with In testimony that I claimthe foregoing I the plate q, having the flanges 1, substantially havehereunto: set my hand this 29th day of as shown and described. December,1875.

6. The combination of the plunger and op- 1 eratingwheel with the cam m,cutting-lever ARTHUR L n, rollers 4, and guide I, whereby the wire isWitnesses: measured, out, and bent at the same motion, GEO. H. MCURAITH,substantially as shown. PETER MARHAVER.
